Abstract
The utility model discloses an ultra-precise capacitor with a polycarbonate film adopted. The ultra-precise capacitor comprises a plastic housing prepared by PBT high-temperature-resistant material, an intermediate medium arranged in the plastic housing and prepared by a metalized polycarbonate film and a pair of pins, wherein one end of each pin is connected with a side surface of the intermediate medium, the other end of each pin extends out of the plastic housing, and the plastic housing is filled with epoxy resin. The plastic housing is used for installing cores and packaging, and then the epoxy resin is used for sealing processing. The capacitor is excellent in electric performance, reliable, high temperature resisting, small in size, and long in service life. Besides, volume of the capacitor changes little along with the changes of the temperature, so purpose of the capacitor is realized.
